CHROMIUM: bluetooth/sco - Check for NULL socket in receiving sco data
When recv_scodata is called, the hci_conn may actually hold a NULL
sock hence accessing the settings of sco_pinfo causes crash.
Fix this by moving the hci_conn socket NULL check earlier, to make
sure we access valid sco_pinfo settings before taking care of HCI SCO
header and call to sco_recv_frame.
BUG=chromium:980454
TEST=Repeatedly stress wideband speech with BT headset, verify
kernel doesn't crash.
